Question Anybody familiar w/ 'Ground Control' coil-over kit?

I talked to a dealer at a local performance shop that I used to get parts for my Civic from. He was showing me the above mentioned brand of coil-over for my RS.
Is this a reliable product?
Supposedly this just replaces the stock spring section of my suspension. He quoted me at about $350 for the kit.
From what I've heard others doing, this is relativly cheap.

Does anyone have any other suggestions? I just want to give my car a lower look (preferably adjustable) but can't spend what I've seen others spend on their suspensions.

I guess what I'm really asking is if this would be complete in the process or would I have to make other mods to the suspension to protect from any damage..(i.e. just using lowering springs w/out replacing the struts and camber etc.)
Sorry so long, just would like to be 100% informed on my decision.

as long as you don't up the spring rates too much and don't drop that car a whole lot the GC setup will work with the stock struts. You also don't need to worry about camber when dropping the car like with Hondas

Ditto

Call them directly (530) 677-8600 after you read the material on this board. Talk to Tony. Good luck!

splelling!

Yeah...everyone has great things to say about them.
Just one more question!!!
Would it be ok to use the coil-over kit with the stock struts? From what I've read in my searches here...everyone suggests the KYB(?)struts. 800 bucks is a little spendy right now...but I can handle the 350 for the coil-overs.

GroundControl makes two versions for our cars, ones that fit on the stock struts(version 5s also) and one for the Kyb AGX struts(I think they will work on any KYB strut). So if you buy them and ue them on your stock struts you can't buy the KYB later without have to buy a new set of the ground controls. This is what i was told buy Ground Control people.

Question

What really are the advantages of going with the aftermarket struts as opposed to sticking with the stock ones?

Will they help keep my ride stiff, where the stock struts lowered will be bouncy?

You get what you pay for! They are the best FAKE coilover kit because they come with EIBACH springs. I would definately choose these over Weapon R or Skunk, but I would much rather save up and go for a REAL coilover kit, like TEIN,or G|A|B|

Yeah, okaaay. What experience do you have with GC's? And weren't you the one trying to get rid of the GAB's because you couldn't adjust them properly?

And what's wrong with Eibachs? Too inexpensive for you? They use Eibachs on real racing cars, you know. These are Eibach race springs and because of their small diameter, will only fit on a coilover setup.

ColinL,

We've got some issues to get through if we are going to run that low. The back is best, by far. No mods required from that height with an additional 2 inches of travel in bump.

The front is a different story altogether. The driveshaft will hit the chassis just before full bump (2 inches). We'll have to cut a seam out of the lower frame to get another cm of travel. Also, the curve of the fender well will interfere with turning the wheel near full bump, so we have to hammer out some room to allow enough steering.

We've got to take it out and test with different ride heights and all. It will be interesting to see how it behaves. In that picture, the lowest part of the car is barely 3 inches off the ground.

3355-
The advantage of the KYB/AGXs over stock struts when used with aftermarket springs is that the spring won't overpower the strut (as long as they are paired correctly).

Also, the KYBs are adjustable while stock is not. I can run stiffest setting for a track day, medium on the twisty roads around home and soft for a freeway trip. Worth the extra dough to go with both.

Anyone know who should I talk to at Ground Control to order a set of those? And how much?
I am looking to use it in autoXs. So I think 8" is good with me. Can it go back to stock height?
What spring rate to use? I am pairing it with KYB AGX. Thanks.

adamsrs,

Sorry, but I have to disagree with you about a fake coilover. The pictures below show the Ground Control Advance Design double adjustable racing struts with Ground Control adjustable spring perches and Eibach racing springs. This setup also has beefy Ground Control Camber/Caster plates for up to -3.5 degrees of camber.

This is a full race suspension from Ground Control. The adjustable perches and sleeves on this racecar are the same ones that you can put on your stock shocks. Just because GC offers an extremely wide range of options for their customers doesn't make any of their stuff "fake." There is nothing "fake" about this stuff. Spend what you can. GC can take care of your needs.

uh, you weren't kidding when you said (in Motorsports) that the car was low Gary!

is the suspension geometry OK at that height? I would think the some of the rear arms & links in particular...

GC is a great way to go. Tony is very smart but you might be on hold for a while. Also do not call around lunch time.

If you want a little below stock height to 2" below stock height, get 8" springs. 10" springs will give you +/- 1" from stock. This is on a GC8 Impreza.

How do you know how low each corner are when you adjust them? Is there a guide say, one twist = 1" of drop?
And when you adjust the height say raise it in the winter and lower it in the summer, do i have to go for alignment again?

Thanks

Nope, if you wanna do it at home, you just raise a corner, twist the collar, lower the car, remeasure, etc.

jdogg: i was in the same situation that you are in now... should i just get the GC or GC/AGX? i just went ahead with the combo because other owners of GC of other cars told me that they blew their shocks quickly. didn't want that happening with me.

tony hooked me up with a 'show setup' which includes the GC, 7" spring 350F/300R, and the AGX. most others went with the 8" spring. measuring from the edge of the wheel well to the center of rim... i was able to get the car 3" lower.

i ride at mid height everyday, and slam at shows. the shocks are wonderful... but like most would agree not the best. however, for my budget, i'm happy.

later on though, i'll switch out to one of those bigger names... simply because its always nice to have a 'big-boy brand name' on the car.

$350 is a good price, but wait and save up for the shocks as well! that 299... last i checked that was for the limited edition setup for the civics and integras.

good luck!

I already have AGX shocks. Just need to get the GC coilovers. So what is the price of the coilovers run on GC? $299? If so, I am sold! Only thing I like to know is the proper spring rate. But I guess Tony of GC can sort me out. is 275F/225R good for weekend autoXs? I like to have some level of comfort too. Is 300F/250R too stiff for the AGX to operate? I heard the AGX can work only to a certan amount of spring stiffness.
Thanks for all the info!
